Hydrolytic Degradation of Polyethylene Terephthalate by Cutinase Enzyme Derived from Fungal Biomass–Molecular Characterization
AI summary Read the abstract
Researchers isolated cutinase and lipase enzymes from Aspergillus tamarii and Penicillium crustosum fungi and demonstrated their ability to catalyze hydrolytic degradation of PET plastic, offering a potential biological route for plastic waste breakdown.
Polyethylene Terephthalate (PET) is utilized worldwide in plastic items, and its aggregation in the earth has turned into a worldwide concern. The hydrolysis of PET was done by cutinase and lipase enzyme. Lipase and cutinase enzymes were extracted from the fungal species isolated from soil. The isolated fungal species were identified as Aspergillus tamarii and Penicillium crustosum by 18S rRNA sequencing. Biodegradation test, cutinase enzyme-catalyzed PET hydrolysis, and different assays were conducted to elucidate PET hydrolysis by the extracted enzymes. These components incorporate cell surface connection inside biofilms, enzyme catalysts engaged with oxidation or hydrolysis of the plastic polymer, metabolic pathways in charge of take-up and osmosis of plastic parts, and synthetic factors favorable or inhibitory to the biodegradation procedure. The degradation of plastic was identified with terephthalic acid release (TPA) release as they are made of two monomeric units. Characterization studies such as FTIR and SEM analysis have exhibited loss of weight or change in physical properties, such as elasticity and the examination of Spectroscopic.

AI summary Read the abstract
Researchers used computer modeling to test whether a fungal enzyme called cutinase could break down nine types of synthetic plastics, finding strong binding affinity for PET, PCL, and several biodegradable plastics — pointing toward biological tools that could help degrade plastic waste in the environment.
Fungal Cutinase-Like Hydrolases As Prospective PET-Degrading Enzymes: An In Silico Analysis
AI summary Read the abstract
Scientists used computer modeling to show that certain fungal enzymes have a similar shape and chemical "toolkit" as bacteria already known to break down plastic bottles (PET plastic). This matters because plastic waste breaks down into microplastics that are showing up in our food, water, and even our bodies—so finding more natural ways to break down this plastic could eventually help reduce our exposure to it. Note that this is an early-stage computer analysis, not a lab test, so real-world proof that these fungal enzymes actually degrade plastic still needs to be confirmed through experiments.
Microbial Polyethylene Terephthalate Hydrolases: Current and Future Perspectives
AI summary Read the abstract
This review surveys microbial enzymes capable of breaking down PET plastic, focusing on the structure and function of key hydrolases like PETase and cutinases. Researchers found that while several enzymes show promising PET-degrading activity, most work slowly and under limited temperature conditions, with engineered variants showing improved performance. The study highlights both the potential and the current limitations of using biological approaches for plastic waste management.
Fungal Cutinase-Like Hydrolases As Prospective PET-Degrading Enzymes: An In Silico Analysis
AI summary Read the abstract
Scientists used computer modeling to show that certain fungal enzymes have a similar shape and chemical "cutting tools" as a bacterial enzyme already known to break down plastic bottles (PET). This matters because plastic pollution and the microplastics it creates are showing up in our food, water, and even bodies — and finding new enzymes that can break down this waste could lead to better tools for cleaning up plastic before it becomes the tiny particles linked to health concerns. This is still early-stage, computer-based research, so real-world lab testing is needed to confirm these fungal enzymes actually work in practice.
